My invention relates to improvements in adjustable tables and benchesand it more es-' pointed out in the annexed claims.

The purpose of my invention is to provide tables and benches indiflerent sizes for children or adults; that are simple to make; thatare inexpensive that can be shipped in knock down condition; that areeasily assembled; that are readily adjusted'to different heights andthatmay, if desired, cooperate'with educationaldevices which can beassembled on the table by sliding ontothe table top or otherwise. j Withthese and other ends in view I illustrate in theaccompanying drawingsuch in-' stances of adaptation as will disclose the broad underlyingfeatures without limiting myself to the specific details shownthereon Ima use any desired cooperating features which lend themselves to theaccomplishment of my purpose. The table top anddra-wer" anddescribedherein.

These parts are so arranged that theentire table or bench may be easily set up by an inexperienced person.By resasonof this, it is possible to have the tables or benchesdelivered directly to the users home at small transportation charges.Another important feature is making the I tables and benches adjustableto varying heights 'and in burying the guiding plates which hold theadjustable portion in proper alignment with the stationary part of thesup- Whether a table top lor a bench seat 26 is ference-being that theparts required for *bench are. smaller 111 slze when the bench is to beused Wltll'l given size of table. Otherwise, if the benchis tobe usedindependently of the'table, its minimum height and length may bewhatever the. exigencies of actual use may demand. In a similar sense,the table itself may be proportionately increased or decreased in sizeas desired. 7

On the under side of the table top 2 or the bench seat 26, side rails 2are attached byme ans of screws. When these rails are attached to atabletop they have a drawer ledge formed 011 their inside top corners onrails 2 are ordinarily attached toa seat-26 viously theledges 5 will beomitted. On the -'other hand, if a drawer should be desired he supportedon ledges formed on side rails 2 in a similar manner to' the use madeof; such ledges on the table.

The side rails 2 are mortised at 1 to receive the tenons S of thesliding support 7. These parts may be glued to each other or ermanentlysecured in any other manner. lhe sliding supports 7 have holes 10 bymeans of which the table top may be held at difterent heights on thetable legs 13 and 13a. Guide plates 9 are driven into lengthwise groovesformed in the edges of the support 7. These guide plates slide ingrooves 14 of the legs 13 and 13a, which construction leaves the outsidefaces of the supports 7 and the legs 18 and 13a flush with each other.The upper ends of the legs 13 and 13a are drawn toward each otheragainst the sliding supports 7 by means of clamps 19. These clamps are.U- shaped so as to permit the legs 13 and 13a and the support 7 to bepositioned between the side members of the clamps. The clamps 19 arepivoted at 20 to the extreme upper ends of the legs 13a and are providedwith clamping thumb screws 21 which are sea-ted in bushings 22 that areimbedded in the upper ends of the legs 13. Bolts '23 pass throughopenings 10 of the supports 7 and through suitable openings in theclamps 19 so as to firmly hold the table in different heightadjustments. lVing nuts 24l ion the outer ends of the bolts 23 serve tohold the bolts 23 in position. These bolts have square shoulders underthe heads which engage slots in the clamps 19 and are thus preventedturning while the wing nuts 24 are put into place.

The feet 11 for the table legs are mortised at 12 to receive the tenons16 of a pair of legs 13 and 13a. They are joined at their lower ends bytie blocks 15 which maybe permanently secured to the legs by gluing, theuse of corrugated fasteners 27 or they may beheld rigidly connected toeach other in any other manner. When so assembled, :a pair ,of legs 13and 13a with a tie block 15 comprise a single unit to be assembled witha single foot 11 by means of the tenon 16 entering the mortise 12 wherethe parts are permanently attached to each other by gluing orvotherwise.

The use of clamps 19 overcomes and avoids the necessity of extreme closefitting of the supports 7 and the table legs. In addition, all tendencyto wobble of the supports 7 in the legs, is overcome through the use ofthe clamping screws 21. In thessteps ofmanufacture the grooves 14 on theinner edges of the table legs are usually sawed throughout their lengthand, if desired, short metal plates similar to the guide plates .9, may'be inserted in the grooves 14: fatathe lower ends of the -legs and suchshort length plates may enter grooves formed in the blocks if suchadditionalreinforcing is desired.

A pair of feet '1; are held vspaced .apartzby a foot rest or crossmember 17, the ends of engaging;

which are seated in vertical gains formed in the tie blocks 15 where theparts are held in assembled relation by screws 18.

In knock-down shape, the table top 1 is separated from the under rails2. A rail 2 and a support 7 form one of a pair of units; a pair of legs13, 13a and a foot 11 form one of a pair of leg units, while the drawer6 and the cross member 17 form independent units.

All of these may be packed together in small space and placed in acarton to be sent by parcel post or otherwise.

If desired, side springs may be attached to the drawer as shown in Fig.7 to overcome any tendency to slide too freely should the table to t'heheles 10, eyelets shown in 'llig. -ilmay be used if desired.
